             Summary: Add Blacklisting of Executors & Nodes within one TaskSet
                 Key: SPARK-17675
                 URL: https://issues.apache.org/jira/browse/SPARK-17675
             Project: Spark
          Issue Type: Task
          Components: Scheduler
    Affects Versions: 2.0.0
            Reporter: Imran Rashid
            Assignee: Imran Rashid


This is a step along the way to SPARK-8425 -- see the design doc on that jira for a complete discussion of blacklisting.

To enable incremental review, the first step proposed here is to expand the blacklisting within tasksets.  In particular, this will enable blacklisting for

* (task, executor) pairs (this already exists via an undocumented config)
* (task, node)
* (taskset, executor)
* (taskset, node)

In particular, adding (task, node) is critical to making spark fault-tolerant of one-bad disk in a cluster, without requiring careful tuning of "spark.task.maxFailures".  The other additions are also important to avoid many misleading task failures and long scheduling delays when there is one bad node on a large cluster.
